SETTING TEETH.

Specification of Letters Patent No. 8,092, dated May 13, 1851.

To all whom it may concern:

Be it known that I, ADoLPH F. AHRENs, of Philadelphia city and county,in .the State of Pennsylvania, have invented an Improved Method ofInserting Artificial Teeth, and that the following is a full, clear, andexact description of the same, reference being had to the. accompanyingdrawings, making part of this specification, in whichp,

Figure 1 is a front View of one of: my teeth, Fig. 2 a back view, and 3a vertical section thereof, andFig. 4, a view of the tooth with theslide removed.

The same letters indicate like parts in all the figures. l

The object of my invention is twofold: First, to obviate the manydifficulties heretofore attendant upon attaching the teeth to the platewhich is fitted against the roof of the mouth; also, to provide a meansof increasing or decreasing the length of the tooth without removing thesetting, an operation bot-h expensive and disagreeable.

To accomplish these objects I make my artificial tooth with a rebate(11)) on the inner face into which fits a metal slide (b) as representedin Fig. 2. The rebate is lined with foil and fits accurately the metalslide, the upper end of which is soldered onto the plate in the roof ofthe mouth.

The advantage of this arrangement is that when it is desired to removethe teeth, 1t 1s not necessary to disturb the setting, and

if after the tooth is set, the wearer discovers that it is either tooshort or too long the defect can be remedied (if in the latter case) byshortening the slide which enters the rebate in the tooth as seen inFig. 2,

if too short it is only necessary to slide thetooth on the metal piecewhich connects it to the roof of the mouth until the required length isattained. Neither in short ening or lengthening the tooth or in removingit from the mouth for cleaning or any other purpose does it becomenecessary to disturb the setting. When the tooth is lengthened bysliding it on the metal piece the hollow space (0) thereby left in thetooth should be filled with any appropriate substance."

What I claim as my invention and desireto secure by Letters Patent isSecuring artificial teeth to a plate in the roof of the month by meansof a rebate in the inner face of the tooth and a slide fitting the sameand soldered or otherwise attachedto the plate in the mouth, for thepurposes and in the manner described.

ADOLPH F. AHRENS.
